Cleaning custard glass

[hazeleyes767]

Does anyobne know what product could be used to safely clean custard glass. I have a beautiful custard compote, which I have cleaned and let soak in dish soap but it still has a dirt mark on the pedestal stem. I was thinking of trying comet, but am afraid of damaging this beautiful dish. Any ideas, suggestions would be greatly appreciated. I do not want to list it with this dirt on it if there is some way I can remove it.

Thanks in advance.

I don't know what custard glass is, but comet would scratch it, as it is a bit abrasive. Hair spray is great for taking off ink and other types of marks off a lot of things, but if there is a coating on the glass, I don't think I would try it..........

I would try a weak solution of warm water and baking powder. (or bicarbonate of soda)

Yes what cheaver said , i use to dig up old Victorian dumps and would put old Bottles in solution of warm water and soda and leave to soak for a day, worked a treat and these bottles had been buried for decades.

What gives custard glass it's creamy appearance is Uranium salts, not normally a problem because the radiation given off by it is very low, no more than one of the old luminous watches.

However, when you come to use powerful chemicals on it, you might be leaching out the Uranium salts with the alkali, which might give you a concentration of Uranium on your hands, and also affect the opalescent creaminess.

I would probably be using strong detergent wearing rubber gloves and on no account soda.

Thanks for all your help. It is appreciated. I sell glassware but have never dealt with custard glass before I got this at an auction in one of those where you have to take two or three things to get the one you want. At any rate, itis pretty and Fenton always sells, I will try the heavy detergent on this. It is just one spot, and we'll see how it goes. Good luck to all in your selling ventures.
